31 courses with the subject ASTR, each shown exactly as we captured it from the college's catalog, with every element we hold. Where the wording looks broken, that is our reading of the catalog, not the college's text.
ASTR 100Understanding the Universe3
Learn how astronomers study and understand the cosmos. Topics include motions of the Sun, Moon, and planets; planetary surfaces, interiors, and atmospheres; telescopes and spectroscopy; prospects for detecting and visiting life elsewhere; how stars are born, age, and die; black holes, dark matter, and gravitational radiation; the Milky Way Galaxy and galaxies beyond; the birth and fate of the expanding Universe. Optional laboratory: ASTR 100L. Optional field experience: ASTR 111.
ASTR 100LAstronomy with Skynet: Our Place in Space1
Students will use UNC's global network of "Skynet" telescopes to observe planets, moons, and other solar-system objects, star-forming regions and clusters, supernova remnants, and galaxies. Through these observations and others, we will reach a better understanding of our place in the universe, and resolve common misconceptions. Topics include: seasons, the Galilean revolution, the cosmic distance ladder, the Great Debate of 1920, dark matter in our galaxy, Hubble's law, dark energy. Previously offered as ASTR 101L.
ASTR 101Introduction to Astronomy: The Solar System3
Celestial motions of the earth, sun, moon, and planets; nature of light; ground and space-based telescopes; comparative planetology; the earth and the moon; terrestrial and gas planets and their moons; dwarf planets, asteroids, and comets; planetary system formation; extrasolar planets; the search for extraterrestrial intelligence (SETI). Honors version available.
ASTR 102Introduction to Astronomy: Stars, Galaxies & Cosmology3
The sun, stellar observables, star birth, evolution, and death, novae and supernovae, white dwarfs, neutron stars, black holes, the Milky Way galaxy, normal galaxies, active galaxies and quasars, dark matter, dark energy, cosmology, early universe. Honors version available.
Humans have always wondered "are we alone?" From discovering life in extreme conditions on Earth, to finding thousands of exoplanets, we now know far more about this question than our ancestors. This class explores our recent understanding of planets, solar systems, where life might be, and how to find it. Optional laboratory: ASTR 100L. Optional field experience: ASTR 111.
ASTR 105Time, Tides, and the Measurement of the Cosmos3
This course is focused on medieval foundations of modern cosmology and is designed to take advantage of the opportunities available for enriched learning in England. The course is problem-based, e.g. How did people reckon calendars, time, and tides, both for navigation and daily life, before clocks and the printed word? Honors version available.
ASTR 110Astrophotography of the Multi-Wavelength Universe3
Students will use UNC's global network of Skynet telescopes to make color images of the moon, planets, star clusters, star-forming regions, star-death regions, and galaxies. They will also use Skynet's radio telescopes to explore the invisible universe, including pulsars, supernova remnants, and supermassive black holes. Astrophotography will be our entry point to deeper explorations of the solar system; star birth, evolution, and death; galaxy formation and evolution; and black holes and Einstein's theory of relativity.
ASTR 111Educational Research in Radio Astronomy1-3
One-week field experience at Green Bank Observatory in West Virginia. Students observe the invisible universe using manually controlled and fully automated radio telescopes, and carry out a variety of observing projects. These target the sun, moon, Jupiter, star-forming regions, supernova remnants, pulsars, the Milky Way and Andromeda galaxies, and more distant, active galaxies and quasars. Students receive training in radio astronomy, attend research and specialty talks, and tour the observatory. Formerly offered as ASTR 111L. Permission of the instructor.
This introductory astrophysics course will focus on the use of classical mechanics, gravitational physics, and the physics of radiation to interpret and explain astronomical observations. Course covers stellar structure, stellar formation and evolution, galaxies, and cosmology with an emphasis on quantitative problem solving.
ASTR 205The Medieval Foundations of Modern Cosmology3
This course will examine science as it emerged and developed in the West starting in the 13th century. We will use example problems from cosmology that are relevant today.
ASTR 448Machine Learning in Physics and Astronomy3
Machine learning is one of the fastest growing and most dynamic areas of modern physics research and data application. This course gives an introduction to the core concepts, theory and tools of machine learning as required by physicists and astronomers addressing practical data analysis tasks. Topics will include, statistics, scientific data set exploration, feature engineering, neural networks, supervised and unsupervised learning. Students will learn how to select and preprocess data, design machine learning models, evaluate model performance, and relate model inputs and outputs to the underlying physics concepts. Some prior programming experience is expected.
An introduction to the study of stellar structure and evolution. Topics covered include observational techniques, stellar structure and energy transport, nuclear energy sources, evolution off the main-sequence, and supernovae.
A capstone research experience introducing modern data-analysis techniques for large astronomical surveys. Students undertake guided research projects with a different theme each semester. The course focuses on real astrophysical discovery of new objects, events and phenomena.
Overview of the structure and evolution of galaxies, with emphasis on learning and applying modern research methods such as scientific literature review and computational astrostatistics. Includes galaxy morphology and dynamics, star formation, active galactic nuclei, galaxy interactions, large-scale clustering, environment-dependent physical processes, and the evolution of the galaxy population over cosmic time.
An introduction to modern cosmology: the study of the contents and evolution of the universe. Covers expanding spacetime, the thermal history of the early universe, including nucleosynthesis and the cosmic microwave background, the inflationary model for the origins of cosmic structure, and the growth of that structure through time.
Surveys the physical processes governing the interstellar medium (ISM), which takes up the "refuse" of old stars while providing fuel for young stars forming. Covers the processes regulating the galactic gas budget and the corresponding observational diagnostics. Topics: radiative transfer, line formation mechanisms, continuum radiation, gas dynamics, star formation.
ASTR 511Atomic and Radiative Processes in Astrophysics3
This course covers key topics in electromagnetism, radiative transport, and thermal and statistical mechanics in the context of astrophysics, such as stellar and planetary interiors and atmospheres, stellar evolution (including star formation and death), stellar populations, and the early universe.
This course provides a broad overview of astrophysical principles underlying stellar and planetary dynamics; N-body dynamics of star clusters, galaxies, and dark matter; fluid dynamics of astrophysical plasmas; and dynamics of the Universe and spacetime.

ASTR 63First-Year Seminar: Catastrophe and Chaos: Unpredictable Physics3
Physics is often seen as the most precise and deterministic of sciences. Determinism can break down, however. This seminar explores the rich and diverse areas of modern physics in which "unpredictability" is the norm. Honors version available.
